Application tiled December E8, 1908. Serial No. 466,540.

l citizen of the United States, residing atBuf` falo, in the count-y of Erie and State of New York, have invented certain new andfuset'ul Improvements in WVindows, of which the following is a specification.

The purpose of this invention is to provide a novel form of window which will adinit of the sash being lowered into an approximately horizontal position, veither for cleaning the glass or for ventilation or other desired purpose, such as replacing a. broken light, for painting or to enable a sash cord to be replaced.

in accordance with this` invention slides are provided and the sashes are pivoted thereto, a catch being provided to hold the sashes to the slides and the latter in turn being provided with catches automa-tic in operation to engage with the frame or caseinent of the window, so as to hold the slides in lowered position when the sashes are swung into an approximately horizontal position, thereby preventingI the counterbalancing means from raising the slides and causing serious inconvenience and trouble.

For a -full understanding ot the invention and the merits thereof, and also to acquire a knowledge of the details oi' construction and the means for eil'ecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure l is a front view of a window einbodying the invention; Fig. 2 is a vert-ical transverse section of the window showing the parts ou a larger scale and having intermediate portionsbroken away; Fig. 3 is a,"

vertical transverse section of the lower portion ot' the window, the sash .being turned into an approximately horizontal position; Fig. l is a horizontal section on the line 4--4 of Fig. 2 showin the parts on a larger scale; Fig. 5 is a orizontal section on the line 5 5 of Fi 2; Fig. (i is a detail perspective view o the frame for reinforcing the grooved portion of the slide; Fig. 7 is a detail perspective view of the catch and the pivot pin connecting the saine to the reinforcing rame illustrated in Fig. 6; Fig. 8 is a horizontal portion of the lower portion ot the traine and sash showing the pivot coinr nection between the sash and slides; Fig. 9 is a detail perspective view of the lower end of n slide; Fig. 10 is a detail `perspective view of a corner portion of the sash; and, Fig. 11 is a detail perspective view of the miner corner portion ofthe lower sash to which the hooked connection is fitted foi' holding the sash parti open for ventilation. Corresponding and like parts arereferred to inthe followin description and indicated in all the views o the drawings by the ,saine reference characters.

, The window may be of any construction or design such as commonly employed in buildings to admit of light and ventilation and comprising a frame and -sliding sash.

The frame or easement 1 is provided with upper and lower sliding sashes 2 and 3, the same being counterbalanced in the accustoined manner to admit of the sash remaining in 'the adjusted osit-ion when raised or lowered to ai desire point. The sliding sashes are of like formation and are similarly equipped, whereby either sash may be swung into an e:pproxinnately horizontal position as requir Inproportioniiig the parts care is to be exercised, so that when the lower sash is elevated to the highest point and the upper sash moved downward to the lowest point, the latter will clear the' former, so as to be swung into horizontal position. If the sa-slies are of equal height it is necsary to provide the upper portion of the frame or easement l with a pocket 4 to receive the upper portion of the lower sash 3 when they saine is elevated to its highest point, so that when the upper sash 2 is lowered it may clear the bottoni rail of the lower sash when swung outward and again back into normal posit-ion.

Each sash is pivoted at its lower end to slides 5 which are mounted in the jambsof the traine or easement, so as to freely slide up and down. Each or' the slides is rabbeted and the rabbeted portion is grooved to provide a tongue 6 and a groove 7, both being ot' approximately V-torni in cross section. The side stiles 8 of the upper, and lower sashes are rabbeted at their outer edges and the rabbeted portions are channeled similarly to the rabbetcd portions of the slides 5 to provide a tongue 9 and a groove 10 which match the corresponding parts 7 and 6 of the slides, thereby providing a close joint, which excludes wind and rain. lt is also observed that the joint formed between a slide and stileinterlock, thereby preventing any lateral play between said parts Patented oct. 1o, 190e.

tongue and groove joint also results in a are in normal position.

drawing together of the slides and st iles when the sash occupies a normal posltlon, that is, with the vslides and stiles in the same plane and secured.

A screw or pin 11 pivotally connects eachof the Slides with a stile of the sash, and to reinforce the pivoted connection a series of washers 12, 13 and 14 are provided These Washers are centrally ,apertured to receive the screw or pivot connection 11. The Washer 14 is connected to a stile of the sash, whereas the Washers 12 and 13 are made fast to lopposite sides of a slide, it being understood that screws or analogous fastenings are employed for securing the several washers to the parts. The Washers 12 and 13 are connected to each other and to the slide by means of fastenings 15 which may consist of machine screws, rivets -or the like. The head of the screw or pivot connection 11 is countersunk in the outer sidev of the Washer 12 and a boss is projected from the inner side of the Washer 12 and is let into the slide and produces an extended bearing for the outer or headed portion of the screw or pivot connection 11.

A lock bolt 16 is fitted to the\upper portion of each of the st iles 8 of the sash and secures the sash to the slides when the parts The lock bolt 16 is slidable in an opening formed in the part 8 and the opening is reinforced by means of a metal sleeve, the latter also forming a stop to limit the outward movement of the lock bolt. The projecting ends of the lock bolts also serve as iinger-pieceswhich are grasped when swinging the sash from or toward a vertical position. 1

The slides 5 `may be directed in their movements b stops or other means usually emplo ed or retaining sliding sashes in place andy counterbalancing the slides and as'shownV Weighted cords 17 are employed, the slides being grooved in their upper portions to receive the end portions of the'cords '17 co erating therewlth. A casting 18 is fitte to the grooved portion. of each slide and reinforces the same and serves as securing means for the cord 17 and provides a suppart fora catch 19 by meansof which the slide is held against vertical displacement when the sash is moved from a vertical into an approximately horizontal osition. The casting 18 constitutes a rein orcing frame which is tted in a recess extending laterally from the groove 2O in which the lower portion of the sash cord 17 is laced. The side members of the reinforcing frame 18 are connected at their lower ends .by means of an integral cross piece 21 in which an opening is formed to receive the lower end of the sash cord, which end is formed into a knot, thereby preventingthe Withdrawal of the sash cord and securing the same to the slide. The vertical or side members of the reinforcing frame 18 are of L-form and are fitted into a recess formed in the edge face of the slide. the outer Wings or flanges of said side members being apertured to receive the fastenings, by means ot which the reinforcing frame is attached to the slide. An opening 22 is formed in a slde member of the reinforcing frame to receive the projecting'end of the lock bolt 16. The catch 19 is located in a recess formed in a. member of the reinforcing frame 18,` so as not to interfere with the vertical movements of the slide. A spring 23 coperates with the catch 19 to project the latter when relieved from restraint whereby it enters a notch 24 in a stop or -the samewvholly Within `the plane of the slides. When the sash is swung outward and downward at its upper end away from the plane of the slides pressure is removed from the projections 25 and the springs 23 coming into play move the catches 19. so as to throw the upper ends thereof outward in position to enter -the notches 24, thereby holding the slides against vertical movement. lVear pieces 26 are fitted to the tongues 9 in position to engage with the projections 25 and thereby prevent indenting and otherwise wearing away of said tongues 9 which would occur if the same were not reinforced.

It is desirable at times to hold the sash open at its upper end to secure ventilation and for this purpose a rod 27 is employed. This rod 27 for convenience is located in a recess 28 formed in the outer side of the top rail of the lower sash, said recess being closed by the lower rail of the upper sash when both sash are closed. The rod 27 is preferably formed at one end with a` hook 29 and at its opposite end with an eye 30. which-is apertured to receive a pin or other fastening 31 by means of which said rod is pivotally connected to t-he top rail ofthe ower sash. When the sash is swung open at its upper end it is made secure by engaging the hook end 29 of the rod 27 with any l convenient portion of the slide upon which the sash is pivoted, the hooked end of the rod contacting with the outer face of the slide.

1t will be readily understood that the invention may be adapted to windows now in use, since the frame or easement is only required to be modified to the extent of forming therein the notches 24, the principal change relating tothe sashes, which latter may be easily removed from the frame or easement and modified to enable the application of the slides 5 thereto, so that the com-v bined width of the sash and slides will not exceed the width of the window frame or the distance between the jambs thereof.`

When vit is required to gain access to the outer side of the sash, for any purpose, as for glazing, cleaning, painting or the like, it is only necessary to move. the sash'downward to its lowest position and withdraw the lock bolt 1G so as to release the upper end of the sash after which the sash may be swung inward and downward. The instant the sash moves a distance sufficient to release the catches 1E). the latter are pressed outward by the springs 23 and engage the notches 24, thereby holding the slides in lowered position and enabling the sash to be swung outward with ease and safety. lVhen the sash is swung upward into a normal posit-ion the projections 25 of the catches 12)'are pressed upon in the manner stated, thereby with- `drawing.: the catches 1t) .from the notches il and after the sash hasbeen secured b v means of projecting the lock bolt 16 into the openings the sash may be moved up or down in the usual manner.

Sashes embodying the invention are not unlike ordinary sashes in general appearance and may be operated in the usual manner` but are accessible upon the outer side for any desired purpose, thereby obvi-ating the dangers incident to sitting upon a window sill and reaching over the sash to operate upon the outer side for any purpose, as when cleaning the window pane, reglazing or other purposes.

Having thus described the invention what is claimed as new is:

l. The combination with a window frame having a sash channel and a locking recess extending into the window frame therefrom.

of a slide n'iovahle in the channehthe inner edge face of the slide being longitudinally grooved from its upper end downward for the reception of the sash cord, said slide being rabbeted in its outer edge face and formed with a longitudinally extending groove, a sash pivoted to the slide, the side bars of the sash being rabbeted-and formed with an outwardly' projecting tongue fitting in said groove, a straight latch bar pivoted at its' middle in a recess formed in the outer edge of the slide to one side of the sash cord groove, whereby the sash cord may pass the latch bar, a spring forcing one end of the latch bar outwardly and into the recess in the sash channel, a projection on the other end of the latch bar extending transversely to the latch bar, through the slide, and into the bottom of the groove formed in the rabbeted face of the slide, sash cord attaching means located in the groove in the slide below the latch bar, and a bolt locking the sash and slide together when the sash has been lmoved far enough to depress said extension of the locking bar and retract the latch.

The combination with a window frame having a sash channel and a recess therein, of al slide movable in the channel, and a sash pivoted to the lower end of said slide, the outer edge of the slide being grooved .on its vupper end for a portion of its length and having a recess extending out from said groove, a reinforcing frame located in said grove on the inside face of the slide and comprising two spaced parallel angle hars connected at their lower ends, a transverse angle bar perforated for engagement with the sash cord,the outwardly projecting flanges of the parallel angle bars fitting over and reinforcing the material of the window sash at the sides of said groove, an angular casing formed integral with one of said bars and fitting in the recess extending from said groove, a latch bar pivoted in said casing, one end thereof adapted to engage with the recess in the channel, the other end having a lateral extension projecting transversely through the slide, into the bottom of the groove on the outer face thereof and into the path of movement of the sash, and a bolt on the sash locking the sash and slide together when the sash has been moved in far enough to depress said extension of the latch bar and retract the latch.

3. In a window, the combination with a frame, of slides mounted in said frame, each of said slides having a circular recess formed in its inside face. a sash having a circular recess formed on each of its outer edge faces, a washer in the recess of the slide, a washer in the recess of the sash, screws holding said washers tixedly in their respective recesses, and a. pint-le passing through the slide,

through both washers, and into a side bar of the window sash, one of said iashers' projecting into the opposed recess, forming a pintle.

L ln a window, the\combinatien of opposed slides movable in the channels of the frame, the inner edge face of each slide being inclined outwardly and toward the middie of the sash and formed with a longitudinally extending inwardly projecting tongue beveled on both sides, each of said slides having a circular recess formed on its inside face extending through said tongue and' into the edge of the slide, a sash having side bars overlapping the slides and having an inclined outer edge face adapted to contact with theinclined inner edge face of the slide and having an outwardly projecty separated from the side bar by a groove fitting the tongue on the slide, the'side edges -of the sash having each a circular recess extending through said tongue and into the body of the side bar of the sash, a washer fixed in the recess on the slide below the level of the beveled inner face thereof, a, washer rigidly fixed in each recess of the sash, projectin outv from the face of the sash interior y of the tongue and extending across the space between the face of the sash bar and the tongue, and a pintle passing through the slide, through both of said washers and into a side bar of the window sash.

In testimony whereof I affix my signature in presence of two witnesses.
